barring question

[TK Poultry]

ok i have one white rock and i have 4 barred and im looking into a barred roo but i didnt want to put the white by herself so if i breed her to a BR the roo would give two copies of the barring gene and the mom wouldnt give any but the barring would be dominate so i would still get barred chicks would that white dilute the barring tho???

A bird never gives two copies of a gene--only one. The barring gene is sex-linked, so females only have one copy, which they inherit from their father. Males inherit a copy from each parent. With barring, the two versions (alleles) for this gene location are barred (B) or not-barred (b+).

Not sure if rocks tend to carry dominant or recessive white. If dominant, the offspring will receive a copy (I assume she carries two copies of the gene: I/I) and be white, although red will show through. She may or may not carry barring--white hides it.

If recessive white, the offspring will not be white--two copies are needed--unless the male carries a copy. Once again, it is hard to say what colour or pattern genes she carries. More will show up in this cross than in a cross to a dominant white. Barring would show if the birds inherit it.

I might be wroung but I think that they might be Sex-linked..
I do know that some of the White Plymouth Rocks are a Sport that came from the Barred Plymouth Rock.. The cross of a Barred Rock Rooster over a White Rock Hen will give you a Silver Barred hybrid..

Aren't white rocks supposed to be silver? With white to cover the black in tail????? Or is i just Rhode Island Whites which are silver.

Don't know--when I hear white bird, I assume white, either dominant or recessive. Will silver cover that much of a bird's plumage?

White rock should be dominant and recessive white. most white birds are actually silver and black. The white gene (dominate or recessive) will remove the black from the feathers. the barred bird is black and carries the sex linked barring gene.

if you mate the white rock hen and the barred rock roosters ALL of the chicks will have the sex link barring gene, they will also be Extended black and Silver

good luck....

I don't really know, but I don't know that silver with Columbain &/or dark brown columbian would make a completely white bird. I'd guess some other white would be needed to cover the white in the tail & flights. But they do say some of these whites are silver & can be used for silver/gold sex links.​

most white birds are, E/E, S/S , w/w , Id/Id, I/I, c/c, Co/co

Extended black, Silver, yellow skin, dermal inhibitor, dominant and recessive white, Columbian and other restrictors/modifiers can clean up white.

 

[Krys109uk]

There are lots of variations which make white birds. Any bird which is c/c is going to be white.

I haven't played much with white birds just white leghorns & some white wyandottes.
My white leghorns were E/E, B/B (B/-), S/S (S/-), I/I, w/w, Id/Id (Id/-).
My white wyandottes which were eb/eb, Co/Co, S/S (S/-), Pg-Ml/Pg-Ml, I/i+, c/c, w/w, Id/Id (Id/-),
